I have a prepaid debit card with $100 on it and i have another vanilla visa gift card with $100 and i want to buy an itouch off of amazon. Is there any way i can use both cards to purchase since there isnt enough on one? Or is there a way to send money from one card to another to pay for it??

Heres an example:
Lets just say you want to buy a $130 radio but you had two Debit cards. One has $100 dollars on it and the other has $40. Could you merge the two cards together in order to purchase this radio?
